Secure Hash Algorithm (SHA) 256 Support

SHA-256, also known as SHA-2 support is available for DigiCert Code Signing starting April 1st, 2013 at no extra charge. SHA-2 was developed by National Institute of Standards and Technology (NIST) and is the recommended cryptographic hash function to replace SHA-1 by the end of 2014.


The option for SHA-2 is available through the ordering pages, reissue process and via the API for QuickOrder, QuickInvite and Reissue.


Some older applications and operating systems may not support SHA-2, for example, Windows XP Service Pack 2 or lower does not support the use of SHA-2. Java SDK 1.4.2 or higher needs to be installed and used on the server for SHA-2 support for Java server support.
